Description

Method, device and system for scheduling logical channel

Technical Field

The embodiment of the invention relates to the field of communication, in particular to a method, a device and a system for scheduling a logical channel.

Background

The rapid development of the 5th Generation mobile communication technology (5G) has made mobile communication have a great impact on people's life and work. The application scenario of 5G generally includes: enhanced Mobile bandwidth (eMBB), massive Machine Type Communications (mtc), and Low-Latency high-reliability Communications (URLLC). Because the URLLC service has high requirements on service delay and service reliability, how to ensure the service requirements of other logical channels becomes an urgent problem to be solved on the premise of ensuring the URLLC service requirements.

Before sending uplink data to a network device, an existing terminal device first needs to receive uplink scheduling resources sent by the network device. Since the total amount of the uplink scheduling resources is determined, the terminal device needs to determine how much uplink scheduling resources can be allocated to each logical channel through a certain rule. Generally, a terminal device determines how much uplink scheduling resources can be allocated to each logical channel through logical channel configuration, where the logical channel configuration is a Priority Bit Rate (PBR) or a Logical Channel Priority (LCP) for logical channel scheduling. After the terminal device allocates uplink scheduling resources to each logical channel, if the uplink scheduling resources allocated to a certain logical channel cannot meet the requirement for scheduling the buffer in the logical channel, the terminal device needs to modify the logical channel configuration of the logical channel in Radio Resource Control (RRC) configuration.

However, the procedure of modifying the logical channel configuration of the logical channel in the RRC configuration by the terminal device (this procedure is also referred to as RRC reconfiguration procedure) is cumbersome, and may cause backlog of the buffer inside the logical channel. Meanwhile, modifying the logical channel configuration of the logical channel in the RRC reconfiguration process may generate more RRC signaling, which affects the performance of the terminal device.

Disclosure of Invention

Embodiments of the present invention provide a method, an apparatus, and a system for scheduling a logical channel, which can dynamically send a logical channel scheduling indication message to a terminal device, thereby ensuring that the configuration of the logical channel meets the requirement of real-time scheduling, and improving the transmission performance of the terminal device while saving RRC signaling overhead required by the configuration of the logical channel.

In order to achieve the above purpose, the embodiment of the invention adopts the following technical scheme:

in a first aspect, an embodiment of the present invention provides a method for scheduling a logical channel, where a terminal device receives control information sent by a network device, where the control information includes logical channel scheduling indication information (including an indication for indicating that a logical channel does not support multiplexed logical channel individual call resources, an indication for logical channel scheduling PBR, or an indication for logical channel priority LCP), and then the terminal device obtains an uplink scheduling resource for sending logical channel data according to the received logical channel scheduling indication information. Therefore, the terminal device can directly receive the control information sent by the network device, where the control information includes an indication for indicating that the logical channel does not support the multiplexed logical channel individual call resource, and a PBR or LCP for logical channel scheduling, and thus obtains the uplink scheduling resource for sending the logical channel data through the indication for indicating that the logical channel does not support the multiplexed logical channel individual call resource, and the PBR or LCP for logical channel scheduling. Compared with the traditional RRC reconfiguration process, the method dynamically sends the logic channel scheduling indication information to the terminal equipment, ensures that the configuration of the logic channel meets the requirement of real-time scheduling, and simultaneously saves the RRC reconfiguration process required by the configuration of the logic channel by sending the PBR indication of the logic channel scheduling or the logic channel scheduling indication of the LCP indication through the control message, thereby saving the RRC signaling overhead and improving the transmission performance of the terminal equipment.

In a first implementable manner of the first aspect, if the logical channel scheduling indication information is an indication that the logical channel individually invokes a resource, a process of the terminal device receiving the control information sent by the network device is as follows: the method comprises the steps that terminal equipment receives a Radio Resource Control (RRC) reconfiguration message sent by network equipment, analyzes the RRC reconfiguration message and obtains an indication that a logical channel independently calls resources; therefore, the terminal equipment obtains the uplink scheduling resource which can be independently called and allocated for the logic channel by the network equipment according to the indication of independently calling the resource by the logic channel.

In a second implementable manner of the first aspect, if the logical channel scheduling indication information is an indication of PBR or an indication of LCP for logical channel scheduling; then the process of the terminal device receiving the control information sent by the network device is as follows: the terminal device receives a Control message (such as a Physical Downlink Control Channel (PDCCH)) or a Medium Access Control (MAC CE) Control element sent by the network device, where the indication of the PDCCH includes an indication of a logical channel scheduled PBR or an indication of an LCP, and the indication of the MAC CE includes an indication of a logical channel scheduled PBR or an indication of an LCP; and the terminal equipment analyzes the control information to obtain the indication of the PBR or LCP of the logic channel scheduling. And the terminal equipment obtains the PBR scheduled by the logic channel according to the indication of the PBR scheduled by the logic channel, and allocates uplink scheduling resources for the logic channel, or obtains the LCP according to the indication of the LCP, and allocates uplink scheduling resources for the logic channel.

The scheduling method of the logical channel provided by the embodiment of the invention can reasonably acquire the uplink scheduling resource for sending the data of the logical channel from two different angles, thereby ensuring that the logical channel configuration of the logical channel is consistent with the requirements of real-time scheduling: one is that a certain amount of uplink scheduling resources which can be called independently are distributed to the logic channel by the network equipment; one is to use a new logical channel configuration sent by the network device to replace an old logical channel configuration inside the terminal device, so that the terminal device uses the new logical channel configuration to allocate uplink scheduling resources to the logical channel.

Optionally, the terminal device may further update and store the PBR or LCP scheduled by the logical channel. Therefore, the timeliness of the PBR or LCP of the logical channel scheduling stored in the terminal equipment is guaranteed.

Further, the logical channel scheduling indication information is scrambled by an RNTI of a logical channel corresponding to the logical channel scheduling indication information or an RNTI dedicated to a radio bearer. After receiving the control information sent by the network device, the terminal device descrambles the scrambled logic channel scheduling indication information, so that the terminal device can know which logic channel the logic channel scheduling indication information is directed to.

Further, the size of the indication of the PBR of the logical channel scheduling is 1 bit or 2 bits; the size of the indication of LCP is 1 bit or 4 bits.

Optionally, when the size of the indication of the PBR of the logical channel scheduling is 1 bit, taking 2-bit as an example, if the indication of the PBR is 0, it means that the PBR of the logical channel is not changed, and if the indication of the PBR is 1, it means that the PBR of the logical channel is set to infinity.

Optionally, when the size of the indication of the PBR of the logical channel scheduling is 1 bit, taking 2-bit as an example, if the indication of the PBR is 0, it indicates to adjust the PBR of the logical channel up to the next value range, and if the indication of the PBR is 1, it indicates to adjust the PBR of the logical channel down to the next value range.

Optionally, when the indicated size of the PBR for logical channel scheduling is 2 bits, taking 2-bit as an example, if the indicated size of the PBR is 00, it means that the PBR of the logical channel is adjusted to 25% of the old PBR inside the terminal device, if the indicated size of the PBR is 01, it means that the PBR of the logical channel is adjusted to 50% of the old PBR inside the terminal device, if the indicated size of the PBR is 10, it means that the PBR of the logical channel is adjusted to 100% of the old PBR inside the terminal device, and if the indicated size of the PBR is 11, it means that the PBR of the logical channel is adjusted to 200% of the old PBR inside the terminal device.

Optionally, when the indicated size of the LCP is 1 bit, taking 2-bit as an example, an indication of the LCP is 0, which indicates that the LCP of the logical channel is turned up to the next value range, and an indication of the LCP is 1, which indicates that the LCP of the logical channel is turned down to the next value range.

Optionally, when the indicated size of the LCP is 4 bits, the 4 bits show the high and low of the LCP.

In a second aspect, an embodiment of the present invention provides a method for scheduling a logical channel, where a network device obtains logical channel scheduling indication information (including an indication for indicating that a logical channel does not support multiplexed logical channel individual call resources, an indication of a prioritized bit rate PBR for logical channel scheduling, or an indication of a logical channel priority LCP), and then sends control information including the logical channel scheduling indication information to a terminal device.

Optionally, if the logical channel scheduling indication information is an indication that the logical channel individually invokes the resource, the process of sending the control information to the terminal device by the network device is as follows: the network device sends an RRC reconfiguration message to the terminal device including an indication that the logical channel invokes the resource alone.

Optionally, if the logical channel scheduling indication information is an indication of PBR or an indication of LCP for logical channel scheduling, the process of sending the control information to the terminal device by the network device is as follows: the network device sends a control message (a Physical Downlink Control Channel (PDCCH) or a control element (MAC CE) of media access control) to the terminal device, wherein the indication of the PDCCH comprises an indication of PBR of logical channel scheduling or LCP, and the indication of the MAC CE comprises an indication of PBR of logical channel scheduling or LCP.

Further, the logical channel scheduling indication information is scrambled by an RNTI of a logical channel corresponding to the logical channel scheduling indication information or an RNTI dedicated to a radio bearer.

Optionally, the indicated size of the PBR for logical channel scheduling is 1 bit or 2 bits; the size of the indication of LCP is 1 bit or 4 bits.

In a third aspect, an embodiment of the present invention provides a method for scheduling a logical channel, where a terminal device receives first control information including logical channel scheduling indication information (where the logical channel scheduling indication information is an indication that a logical channel calls a resource independently or an indication that the logical channel does not call the resource independently) sent by a network device; after the terminal equipment confirms that the logical channel scheduling indication information is the indication for the logical channel to independently call the resources, the terminal equipment acquires the uplink scheduling resources which can be independently called and are allocated to the logical channel by the network equipment according to the logical channel scheduling indication information. It can be seen that, in the scheduling method of a logical channel provided in the embodiment of the present invention, a terminal device may first receive first control information including logical channel scheduling indication information sent by a network device, and determine whether the logical channel scheduling indication information is an indication for a logical channel to separately invoke resources. If the logical channel scheduling indication information is an indication that the logical channel individually invokes the resource, the terminal device can directly obtain the uplink scheduling resource that is allocated to the logical channel by the network device and can be invoked individually. Compared with the traditional RRC reconfiguration process, the method and the device can dynamically send the logic channel scheduling indication information to the terminal device, ensure uplink scheduling resources which can be independently called and can be owned by the logic channel, enable the logic channel configuration to meet the requirement of real-time scheduling, and improve the transmission performance of the terminal device.

Further, the method for scheduling a logical channel provided in the embodiment of the present invention further includes: after the terminal equipment confirms that the logical channel scheduling indication information is the indication of the logical channel non-independent calling resource, the terminal equipment receives second control information which is sent by the network equipment and comprises the indication of the logical channel scheduling priority bit rate PBR or the indication of the logical channel priority LCP, and obtains the uplink scheduling resource for sending the logical channel data according to the indication of the logical channel scheduling PBR or the indication of the LCP. It can be seen that, when the logical channel scheduling indication information is an indication that the logical channel does not independently invoke resources, the embodiment of the present invention can also send, by the network device, second control information including an indication of a priority bit rate PBR for logical channel scheduling or an indication of a logical channel priority LCP, and the terminal device replaces an old logical channel configuration inside the terminal device with a new logical channel configuration sent by the network device, so that the terminal device allocates uplink scheduling resources to the logical channel using the new logical channel configuration. Meanwhile, compared with the traditional RRC reconfiguration process, the method omits the RRC reconfiguration process required by the logical channel configuration and saves the overhead of RRC signaling.

Optionally, the step of acquiring, by the terminal device, the uplink scheduling resource for sending the logical channel data according to the instruction of the PBR scheduled by the logical channel or the instruction of the LCP is specifically: the terminal equipment firstly obtains the PBR scheduled by the logic channel according to the indication of the PBR scheduled by the logic channel, and then allocates uplink scheduling resources for the logic channel according to the PBR scheduled by the logic channel; or the terminal equipment firstly obtains the LCP according to the indication of the LCP and then allocates uplink scheduling resources for the logical channel according to the LCP. Therefore, the terminal device can use the new logical channel configuration sent by the network device to replace the old logical channel configuration in the terminal device, so that the terminal device uses the new logical channel configuration to allocate the uplink scheduling resource to the logical channel.

Optionally, the logical channel scheduling indication information is scrambled by a radio network temporary identifier RNTI or an RNTI dedicated for radio bearer of a logical channel corresponding to the logical channel scheduling indication information. After receiving the control information sent by the network device, the terminal device descrambles the scrambled logic channel scheduling indication information, so that the terminal device can know which logic channel the logic channel scheduling indication information is directed to.

Optionally, the first control information is a radio resource control RRC reconfiguration message, and the second control information is a physical downlink control channel PDCCH or a control unit MAC CE for media access control.

In a fourth aspect, an embodiment of the present invention provides a method for scheduling a logical channel, where a network device obtains logical channel scheduling indication information (an indication that a logical channel calls resources individually or an indication that a logical channel does not call resources individually), and then the network device sends first control information including the logical channel scheduling indication information to a terminal device.

Further, after the network device sends the first control information to the terminal device, the method for scheduling a logical channel according to the embodiment of the present invention further includes: the network device obtains an indication of a prioritized bit rate, PBR, of logical channel scheduling or an indication of logical channel priority, LCP, and then the network device sends second control information comprising the indication of the PBR, of logical channel scheduling or the indication of LCP, to the terminal device.

Optionally, the logical channel scheduling indication information is scrambled by a radio network temporary identifier RNTI or an RNTI dedicated for radio bearer of a logical channel corresponding to the logical channel scheduling indication information.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

Furthermore, the terms "including" and "having," and any variations thereof, in the description and claims of embodiments of the invention and the drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Embodiments of the invention may be implemented as a computer-implemented process (method), a computing system, or as an article of manufacture, such as a computer program product or computer readable media. The computer program product may be a computer storage media readable by a computer system and encoding a computer program of instructions for causing the computer or computing system to perform an example process. The computer readable storage medium is a non-transitory computer readable memory device. For example, the computer-readable storage medium may be implemented via one or more of a volatile computer memory, a non-volatile memory, a hard drive, a flash drive, a floppy or compact disk, and similar media.

In this embodiment of the present invention, the term "and/or" is only one kind of association relationship describing an associated object, and means that three relationships may exist, for example, a and/or B may represent: a exists alone, A and B exist simultaneously, and B exists alone.

Furthermore, the terms "first" and "second", etc. in the description and claims of the present invention and the accompanying drawings are used for distinguishing different objects and are not intended to limit a specific order.

The technical solution provided by the embodiment of the present invention can be applied to various communication systems, such as the 2nd Generation mobile communication technology (5G), the 3rd Generation mobile communication technology (5G), the 4th Generation mobile communication technology (5G) communication system and the next Generation communication system, for example, 2G systems such as Global System for Mobile communications (GSM), Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, 3G systems such as Wideband Code Division Multiple Access (WCDMA) systems, 4G systems such as Long Term Evolution (Long Term Evolution, LTE) systems, communication systems of LTE advanced systems, and the like.

Taking an LTE system as an example, fig. 1 is an architecture diagram of an LTE system according to an embodiment of the present invention. The LTE system is divided into three network elements: a terminal device, an Evolved Packet Core (EPC) device, and an Evolved base station (eNode B). The EPC is responsible for a core network portion, which includes a Mobility Management Entity (MME) and a Serving Gateway (S-GW), wherein the MME performs signaling processing and the S-GW performs data processing. The eNode B is responsible for the Access Network part, also known as Evolved universal terrestrial Radio Access Network (E-UTRAN). The scheduling method of the logical channel provided by the invention is carried out between the eNode B and the terminal equipment.

As shown in fig. 2, before the existing terminal device sends uplink data to the network device, the terminal device first sends scheduling request information to the network device; the network device then sends uplink scheduling resources for sending a Buffer Status Report (BSR) to the terminal device; after receiving uplink scheduling resources for sending a BSR, the terminal equipment sends the BSR on the uplink scheduling resources; and finally, the network equipment sends uplink scheduling resources for sending uplink data to the terminal equipment. Since the total amount of the uplink scheduling resources for transmitting the uplink data is determined, the terminal device needs to determine how much uplink scheduling resources can be allocated to each logical channel through a certain rule. Generally, the terminal device determines how much uplink scheduling resources can be allocated to each logical channel by using a token bucket algorithm through PBR or LCP for logical channel scheduling. Among them, the token bucket algorithm is one of the most commonly used algorithms in network Traffic Shaping (Traffic Shaping) and Rate Limiting (Rate Limiting), and is used to control the number of data transmitted onto a network and allow transmission of burst data.

However, as shown in fig. 3, it is assumed that there are priorities of 4 logical channels in the terminal device, and the smaller the value of the LCP is, the higher the corresponding priority level is, and different priorities correspond to different PBR values for logical channel scheduling (i.e., the priorities of the 4 logical channels in fig. 3 decrease from left to right in sequence). Since the URLLC service has high requirements on service delay and service reliability, the PBR is configured to infinity (infinity) assuming that it is configured to have a high priority level of 1, that is, only when the resource of this logical channel is satisfied, the logical channel with a lower priority level than that of the logical channel will be considered. This method can preferentially guarantee uplink transmission of URLLC, but may cause accumulation of other low-priority logical channel buffers, and once a low-priority logical channel obtains a scheduling opportunity, the uplink scheduling resources (e.g. resources shown below the dashed line in priority 2, priority 3, and priority 4) allocated to the logical channel cannot meet the requirement for scheduling the buffer (e.g. resources shown in the shaded portion in priority 2, priority 3, and priority 4) in this logical channel, and the terminal device needs to modify the PBR of this logical channel in the RRC reconfiguration process. If the PBR is changed each time, it is possible that the logical channel may not catch up with the scheduled time. Meanwhile, modifying the logical channel configuration of the logical channel in the RRC reconfiguration process may generate more RRC signaling, which affects the performance of the terminal device.

The scheduling method of the logical channel provided by the embodiment of the invention can reasonably allocate uplink scheduling resources to the logical channel of the terminal equipment, thereby ensuring that the logical channel configuration of the logical channel is consistent with the requirement of real-time scheduling, simultaneously saving RRC signaling and improving the performance of the terminal equipment.

Further exemplarily, taking a network device as an eNode B as an example, a general hardware architecture of the eNode B is described. As shown in fig. 5, the eNode B may include an indoor Baseband processing Unit (BBU) and a Remote Radio Unit (RRU), and the RRU is connected to an antenna feed system (antenna), and the BBU and the RRU may be detached for use as needed.

An embodiment of the present invention provides a method for scheduling a logical channel, and as shown in fig. 6, the method includes S101-S104:

s101, the network equipment acquires logical channel scheduling indication information, wherein the logical channel scheduling indication information is any one of an indication of a logical channel for independently calling resources, an indication of PBR for logical channel scheduling and an indication of LCP.

It should be noted that the indication that the logical channel calls the resource alone is used to indicate that the logical channel does not support multiplexing. The indication of PBR of logical channel scheduling refers to a variation rule of PBR of logical channel scheduling in the terminal device. The indication of LCP refers to the change rule of LCP in the terminal device.

The scheduling method of the logical channel provided by the embodiment of the invention can reasonably allocate uplink scheduling resources to the logical channel of the terminal equipment from two different angles, thereby ensuring that the logical channel configuration of the logical channel is consistent with the requirements of real-time scheduling: one is that a certain amount of uplink scheduling resources which can be called independently are distributed to the logic channel by the network equipment; the other method is to use the indication of the logical channel scheduled PBR or the indication of the LCP sent by the network device, so that the terminal device adjusts the logical channel scheduled PBR or the LCP in the terminal device according to the indication, and replace the old logical channel scheduled PBR or the LCP in the terminal device with the adjusted logical channel scheduled PBR or the adjusted logical channel scheduled LCP, so that the terminal device uses the new logical channel scheduled PBR or the adjusted logical channel scheduled LCP to allocate the uplink scheduling resource to the logical channel.

It should be further noted that the logical channel scheduling indication information mentioned in the embodiment of the present invention may be an indication for indicating that the logical channel does not support multiplexing, and the logical channel scheduling indication information is used to indicate that the network device allocates the uplink scheduling resource that can be separately invoked for the logical channel. The PBR and LCP of the logic channel scheduling in the embodiment of the invention both belong to logic channel configuration and are the basis for allocating uplink scheduling resources for the logic channels by the terminal equipment.

It can also be understood that the network device may determine whether to acquire the logical channel scheduling indication information according to various status information sent by the terminal device, may also receive a request message sent by the terminal device, and acquires the logical channel scheduling indication information according to the request message, which is not limited in this invention.

S102, the network equipment sends control information to the terminal equipment, wherein the control information comprises logical channel scheduling indication information.

It should be noted that, if the logical channel scheduling indication information is an indication that the logical channel individually invokes resources, the control information is a radio resource control RRC reconfiguration message; if the logical channel scheduling indication information is an indication of PBR or an indication of LCP for logical channel scheduling, the control message may be a physical downlink control channel PDCCH or a control element MAC CE for media access control. Especially for the condition that the logic channel scheduling indication information is the indication of PBR of logic channel scheduling or the indication of LCP, compared with the traditional RRC reconfiguration process, the method for sending the logic channel scheduling indication information through the control message omits the RRC reconfiguration process required by logic channel configuration, saves the RRC signaling overhead and improves the transmission performance of the terminal equipment.

S103, the terminal equipment receives the control information sent by the network equipment.

And S104, the terminal equipment acquires the uplink scheduling resource for sending the data of the logical channel according to the logical channel scheduling indication information.

Further, the logical channel scheduling indication information mentioned in the embodiment of the present invention is scrambled by a Radio Network Temporary Identity (RNTI) of a logical channel corresponding to the logical channel scheduling indication information or an RNTI dedicated to a Radio bearer. After receiving the control information sent by the network device, the terminal device descrambles the scrambled logic channel scheduling indication information, so that which logic channel in the terminal device the logic channel scheduling indication information is directed to is known.

It should be added that the uplink scheduling resource for transmitting logical channel data mentioned in the embodiment of the present invention may also be referred to as an uplink data transmission resource of a logical channel, and is used for transmitting uplink data of the logical channel.

Next, step S102, step S103 corresponding to step S102, and step S104 will be described in detail:

specifically, as shown in fig. 7, for the case that the logical channel scheduling indication information is an indication that the logical channel individually invokes the resource, step S102 may include step S102 a:

s102a, the network device sends an RRC reconfiguration message to the terminal device, where the RRC reconfiguration message includes an indication that the logical channel individually invokes the resource.

For example, the indication that the logical channel calls the resource alone may be an Information Element (IE), such as a logical channel multiplexing identifier r15 logical channel-multiplexing-mask-r 15.

Accordingly, step S103 may specifically include steps S103aa and S103 ab:

s103, 103aa, the terminal device receives the RRC reconfiguration message sent by the network device.

S103ab, the terminal equipment analyzes the RRC reconfiguration message to obtain the indication that the logical channel calls the resource independently.

When the terminal equipment receives the RRC reconfiguration message sent by the network equipment, the terminal equipment analyzes the RRC reconfiguration message to obtain the indication that the logical channel independently calls the resources, and confirms that the indication that the logical channel independently calls the resources indicates that the logical channel does not support multiplexing.

It should be noted that, if the information unit included in the RRC reconfiguration message indicates that the logical channel supports multiplexing, uplink scheduling resources are allocated to the logical channel according to a conventional token bucket algorithm, which is not limited in the present invention.

Meanwhile, step S104 may include step S104 a:

s104a, the terminal device obtains the uplink scheduling resource which can be individually called and allocated by the network device for the logical channel according to the logical channel scheduling indication information.

For the case that the logical channel scheduling indication information is an indication that the logical channel individually invokes the resource, after the terminal device confirms that the indication that the logical channel individually invokes the resource indicates that the logical channel does not support multiplexing, the terminal device can obtain the uplink scheduling resource that can be individually invoked and allocated to the logical channel by the network device by monitoring the PDCCH according to the logical channel scheduling indication information, so that the logical channel can transmit uplink data to the network device using the allocated uplink scheduling resource that can be individually invoked.

Specifically, as shown in fig. 8, for the case that the logical channel scheduling indication information is an indication of PBR of logical channel scheduling, step S102 may specifically include step S102 b:

s102b, the network device sends a PDCCH to the terminal device, where the PDCCH indication includes an indication of the logical channel scheduled PBR.

Accordingly, step S103 may specifically include steps S103ba and S103 bb:

s103, 103ba, the terminal device receives the PDCCH sent by the network device.

S103bb, the terminal equipment analyzes the PDCCH to obtain the indication of the PBR scheduled by the logical channel.

Meanwhile, the step S104 may include steps S104ba and S104 bb:

s104ba, the terminal equipment obtains the PBR of the logical channel scheduling according to the indication of the PBR of the logical channel scheduling.

Specifically, the indication of the PBR of the logical channel scheduling refers to a variation rule of the PBR of the logical channel scheduling.

In particular, for a logical channel of URLLC traffic, the PBR of the logical channel scheduling may take an infinite value (infinity), i.e. it represents the highest priority of URLLC traffic.

Further, the size of the indication of PBR of logical channel scheduling is 1 bit or 2 bits.

Table 1 shows an indication of a PDCCH according to an embodiment of the present invention, where the indication of the PDCCH includes an indication of a logical channel number occupying 4 bits and a PBR of logical channel scheduling occupying 1 bit or 2 bits.

In a first possible implementation manner, taking 2-ary as an example, when the indicated size of the PBR is 1 bit, a value of 0 for the PBR indicates that the PBR of the logical channel is unchanged (i.e. the PBR is still an old PBR inside the terminal device), and a value of 1 for the PBR indicates that the PBR of the logical channel is set to infinity.

In a second possible implementation manner, taking 2-ary as an example, when the indicated size of the PBR is 1 bit, the indication of the PBR is 0, which means that the PBR of the logical channel is turned up to the next value range, and the indication of the PBR is 1, which means that the PBR of the logical channel is turned down to the next value range.

In a third possible implementation manner, taking 2-bit as an example, when the indicated size of the PBR is 2 bits, the indication of the PBR being 00 indicates that the PBR of the logical channel is adjusted to 25% of the old PBR inside the terminal device, the indication of the PBR being 01 indicates that the PBR of the logical channel is adjusted to 50% of the old PBR inside the terminal device, the indication of the PBR being 10 indicates that the PBR of the logical channel is adjusted to 100% of the old PBR inside the terminal device, and the indication of the PBR being 11 indicates that the PBR of the logical channel is adjusted to 200% of the old PBR inside the terminal device.

It should be understood that the three possible implementations described above are only one implementation of the embodiment of the present invention, and the indications of the PBR for logical channel scheduling of other sizes and the change rule of the PBR for logical channel scheduling also belong to the protection scope of the present invention, and are not described herein again.

Optionally, since the terminal device can distinguish which logical channel information is when decoding the PDCCH, the PDCCH may not carry a logical channel number, as shown in table 2:

It should be noted that, there is no precedence relationship between step S105b and step S104bb, and in the method for scheduling a logical channel according to the embodiment of the present invention, the terminal device may update and store the PBR scheduled by the logical channel first, or allocate uplink scheduling resources to the logical channel first according to the PBR scheduled by the logical channel, which is not limited in this embodiment of the present invention.

Specifically, as shown in fig. 9, for the case that the logical channel scheduling indication information is an indication of PBR of logical channel scheduling, step S102 may specifically include step S102 c:

s102c, the network device sends the MAC CE to the terminal device, where the indication of the MAC CE includes an indication of the logical channel scheduled PBR.

Accordingly, step S103 may specifically include steps S103ca and S103 cb:

s103ca, the terminal equipment receives the MAC CE sent by the network equipment.

S103cb, the terminal equipment analyzes the MAC CE to obtain the instruction of the PBR scheduled by the logical channel.

Meanwhile, the step S104 may include steps S104ca and S104 cb:

s104ca, the terminal equipment obtains the PBR of the logical channel scheduling according to the indication of the PBR of the logical channel scheduling.

Fig. 10 shows an indication of a MAC CE according to an embodiment of the present invention, which includes a logical channel number occupying 4 bits, an indication of a logical channel scheduled PBR occupying 1 bit, and a reserved bit occupying 3 bits. Fig. 11 shows another indication of a MAC CE according to an embodiment of the present invention, which includes a logical channel number occupying 4 bits, an indication of a PBR occupying 2 bits, and a reserved bit occupying 2 bits. The indicated size of the PBR and the variation rule of the PBR are the same as the three possible implementations in step S104ba, and for brevity, are not described again here.

Meanwhile, the step S104 may include steps S104da and S104 db:

and S104da, the terminal equipment obtains the LCP according to the indication of the LCP.

Specifically, the indication of LCP means the change rule of LCP.

Further, the size of the indication of LCP is 1 bit or 4 bits.

Table 3 shows another PDCCH indication provided in the embodiment of the present invention, where the PDCCH indication includes a logical channel number occupying 4 bits and an LCP occupying 1 bit or 4 bits.

In a first possible implementation manner, taking 2-ary as an example, when the indicated size of the LCP is 1 bit, an indication of 0 of the LCP indicates that the LCP of the logical channel is turned up to the next value range, and an indication of 1 of the LCP indicates that the LCP of the logical channel is turned down to the next value range.

In a second possible implementation, taking 2-ary as an example, when the indicated size of the LCP is 4 bits, the high and low of the LCP can be shown directly according to the actual situation.

It should be understood that the three possible implementations described above are only one implementation of the embodiments of the present invention, and indications of LCPs with other sizes and variation rules of the LCPs also belong to the protection scope of the present invention, and are not described herein again.

And S104db, the terminal equipment allocates uplink scheduling resources for the logical channels according to the LCP.

Optionally, after the step S104da is executed, the embodiment of the present invention further includes a step S105 d:

and S105, 105d, the terminal equipment updates and saves LCP.

Similarly, step S105d and step S104db do not have a sequential relationship.

Specifically, as shown in fig. 13, for the case that the logical channel scheduling indication information is an indication of LCP, the step S102 may specifically include the step S102 e:

s102e, the network device sends the MAC CE to the terminal device, and the indication of the MAC CE comprises the indication of LCP.

Accordingly, step S103 may specifically include steps S103ea and S103 eb:

s103ea, the terminal equipment receives the MAC CE sent by the network equipment.

S103eb, the terminal device analyzes the MAC CE to obtain the LCP indication.

Meanwhile, the step S104 may include steps S104ea and S104 eb:

and S104ea, the terminal equipment obtains the LCP according to the indication of the LCP.

Further, the size of the indication of LCP is 1 bit or 4 bits.

Fig. 14 shows an indication of a MAC CE according to an embodiment of the present invention, which includes a logical channel number occupying 4 bits, an indication of an LCP occupying 1 bit, and a reserved bit occupying 3 bits. Fig. 15 shows an indication of a MAC CE according to an embodiment of the present invention, which includes a logical channel number occupying 4 bits and an indication of an LCP occupying 4 bits. The values of the indication of the LCP and the variation rule of the LCP are the same as the two possible implementation manners in step S104da, and for brevity, the description is omitted here.

And S104eb, the terminal equipment allocates uplink scheduling resources for the logical channels according to the LCP.

Optionally, after the step S104ea is executed, the embodiment of the present invention further includes a step S105 e:

and S105, 105e, the terminal equipment updates and saves LCP.

Similarly, step S105e and step S104eb do not have a sequential relationship.

It should be noted that, for the case that the logical channel scheduling indication information is the PBR or LCP scheduled by the logical channel, after the terminal device updates and stores the PBR or LCP scheduled by the logical channel, the terminal device can allocate the uplink scheduling resource to the logical channel according to the stored PBR or LCP scheduled by the logical channel. Meanwhile, the step of updating the PBR or LCP of the logical channel scheduling can ensure the timeliness of the PBR or LCP of the logical channel scheduling in the terminal equipment.

The embodiment of the invention provides a method for scheduling a logical channel, wherein terminal equipment receives control information sent by network equipment, wherein the control information comprises logical channel scheduling indication information, and the logical channel scheduling indication information is any one of indication of a logical channel to independently call resources, indication of a Priority Bit Rate (PBR) of logical channel scheduling and indication of logical channel priority LCP; and the terminal equipment acquires the uplink scheduling resource for sending the data of the logical channel according to the logical channel scheduling indication information. Based on the description of the foregoing embodiments, the terminal device in the scheduling method for logical channels according to the embodiments of the present invention can directly receive control information sent by a network device, where the control information includes an indication for indicating that a logical channel does not support a multiplexed logical channel individual call resource, and a PBR or an LCP for logical channel scheduling, so that an uplink scheduling resource for sending logical channel data is obtained through the indication for indicating that the logical channel does not support the multiplexed logical channel individual call resource, and the PBR or the LCP for logical channel scheduling. Compared with the traditional RRC reconfiguration process, the method dynamically sends the logic channel scheduling indication information to the terminal equipment, ensures that the configuration of the logic channel meets the requirement of real-time scheduling, and simultaneously saves the RRC reconfiguration process required by the configuration of the logic channel by sending the PBR indication of the logic channel scheduling or the logic channel scheduling indication of the LCP indication through the control message, thereby saving the RRC signaling overhead and improving the transmission performance of the terminal equipment.

An embodiment of the present invention further provides a method for scheduling a logical channel, as shown in fig. 16, where the method includes S201 to S205:

s201, the network equipment acquires logical channel scheduling indication information, wherein the logical channel scheduling indication information is an indication that a logical channel calls resources independently or an indication that the logical channel calls resources non-independently.

It should be noted that the logical channel scheduling indication information is used to indicate whether the logical channel supports multiplexing, that is, the indication that the logical channel separately invokes the resource is used to indicate that the logical channel does not support multiplexing, and the indication that the logical channel does not separately invoke the resource is used to indicate that the logical channel supports multiplexing.

Illustratively, the logical channel scheduling indication information may be an identification bit in the first control information mentioned in the following embodiments, taking 2-ary as an example, when the identification bit is 1, it indicates that the logical channel does not support multiplexing (i.e. the logical channel separately calls the indication of resources); when the flag bit is 0, it indicates that the logical channel supports multiplexing (i.e., the logical channel does not separately invoke an indication of resources). It should be understood that the value of the flag bit is only one implementation manner of the present invention, and the values of other flag bits also belong to the protection scope of the present invention, and the present invention is not particularly limited thereto.

It can also be understood that the network device may determine whether to acquire the logical channel scheduling indication information according to various status information sent by the terminal device, may also receive a request message sent by the terminal device, and acquires the logical channel scheduling indication information according to the request message, which is not limited in this respect.

S202, the network equipment sends first control information to the terminal equipment, wherein the first control information comprises logical channel scheduling indication information.

Specifically, the first control information may be a radio resource control RRC reconfiguration message, or may be other types of control information, which is not limited in the present invention.

S203, the terminal equipment receives the first control information sent by the network equipment.

S204, the terminal equipment judges whether the logic channel scheduling indication information is an indication for singly calling the resources by the logic channel.

Specifically, taking the first control information as an RRC reconfiguration message as an example, after receiving the RRC reconfiguration message sent by the network device, the terminal device analyzes the RRC reconfiguration message to obtain logical channel scheduling indication information, and determines whether the logical channel scheduling indication information is an indication for independently invoking resources by a logical channel. If the logic channel scheduling indication information is an indication that the logic channel individually calls the resource, the following step S205 is continuously executed to end the flow of the scheduling method of the logic channel provided by the embodiment of the present invention; if the logic channel scheduling indication information is an indication that the logic channel does not independently invoke the resource, step S205 is skipped, and the following steps S206 to S210 are executed to complete the flow of the scheduling method for the logic channel according to the embodiment of the present invention.

And S205, if the logic channel scheduling indication information is an indication that the logic channel individually calls the resources, the terminal equipment acquires the uplink scheduling resources which can be individually called and are allocated to the logic channel by the network equipment according to the logic channel scheduling indication information.

Further, the logical channel scheduling indication information mentioned in the embodiment of the present invention is scrambled by an RNTI of a logical channel corresponding to the logical channel scheduling indication information or an RNTI dedicated to a radio bearer. For the description of scrambling, reference may be made to the description related to step S104 in the above embodiment, and for brevity, the description is omitted here.

Further, as shown in fig. 17, the method for scheduling a logical channel according to the embodiment of the present invention may further include S206-S210:

s206, if the logic channel scheduling indication information is an indication that the logic channel does not independently call resources, the network equipment acquires an indication of a Priority Bit Rate (PBR) of logic channel scheduling or an indication of Logic Channel Priority (LCP).

It should be noted that, after the terminal device determines that the logical channel scheduling indication information is an indication that the logical channel does not independently call resources, the terminal device may actively request the network device for an indication of PBR or an indication of LCP for logical channel scheduling; the network device may also monitor the terminal device, and actively issue the PBR indication or LCP indication of the logical channel scheduling after the terminal device determines that the logical channel scheduling indication information is the indication that the logical channel does not independently invoke the resource, which is not specifically limited in the present invention.

S207, the network device sends second control information to the terminal device, where the second control information includes an indication of PBR or an indication of LCP for logical channel scheduling.

For example, the second control information may be a physical downlink control channel PDCCH or a control element MAC CE for medium access control. And, compared with the conventional RRC reconfiguration process, the method for transmitting the PBR indication or LCP indication of the logical channel scheduling through the second control message omits the RRC reconfiguration process required by the logical channel configuration, saves the RRC signaling overhead and improves the transmission performance of the terminal equipment.

S208, the terminal equipment receives the second control information sent by the network equipment.

And S209, the terminal equipment acquires the uplink scheduling resource for sending the data of the logical channel according to the instruction of the PBR or the instruction of the LCP scheduled by the logical channel.

Specifically, for the case where the second control information includes an indication of the priority bit rate PBR for logical channel scheduling, as shown in fig. 18, step S209 may include steps S209a and S209 b:

s209a, the terminal device obtains the PBR scheduled by the logical channel according to the PBR scheduled by the logical channel.

S209b, the terminal device allocates uplink scheduling resources for the logical channel according to the PBR scheduled by the logical channel.

Optionally, after the step S209a is executed, the embodiment of the present invention further includes a step S210 a:
